edit_operation
There are already several Python packages that implement levenshtein distance, which are writtend by C or C++ to improve the efficiency. In certain occasions, besides the edit distance, the edit operations are also needed. python-Levenshtein has the editops function but doesn't support transpose operations. So here comes the project, editdistpy supports the function of edit operations under Damerau–Levenshtein distance.
Install
pip install -U edit_operation
Usage
The package supports distance and edit_operations two functions. They have the same parameters
- string a
- string b
- max_distance: Only return right result under max_distance.
- is_damerau: Whether support transpose operation or not.
distance
from edit_operation import levenshtein
a = 'absolute'
b = 'absiluti'
dis = levenshtein.distance(a, b)
return -1 if the actual distance is beyond max_distance, by default max_distance is -1, which means no max_distance limit.
edit_operations
from edit_operation import levenshtein
a = 'absolute'
b = 'bsiluti'
operations = levenshtein.edit_operations(a, b, is_damerau=True)
"""
[{'operation': 'replace', 'location': 7, 'char_x': 'e', 'char_y': 'i'},
{'operation': 'delete', 'location': 0, 'char_x': '@', 'char_y': 'a'}]
"""
@ character means the beginning of the input string. Return empty list if the actual distance is beyond max_distance.
